Timo Walther commented on FLINK-13225:
--------------------------------------

I'm not sure if there was really consensus on having a temporary solution like 
this. The PR was stale also because what it does is very hacky (as mentioned in 
this [PR|https://github.com/apache/flink/pull/8920]) and not supported by 
others. It is true that the PR is already 1 month old but even this date was 
officially after feature freeze. It enables Hive UDFs (which is great!) but by 
avoiding the API and changing a couple of locations in the Blink planner. All 
these changes are instant legacy. I'm fine with not reverting the changes, 
because both Blink and Hive are considered more beta/experimental. But in the 
future I would kindly remind everyone that "feature freeze" means "feature 
freeze".
